Specification of Letters Patent.

Patented Feb. 8, 1916.

Application filed November 10, 1814. Serial No. 871,284.

To all whom it may concern.

Be it known that 1, JOHN M. Kao'rsn, a citizen of the United States, residing at Stockton, in the county of San Joaquin, State of California. have invented certain new and useful Improvements in Air-Humidifiers for l lxplosive-Motors; and I do declare the following, to be a clear, full, and exact description of the same, such as will enable others skilled in the art to which it 'appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon. which form a part of this application.

This invention relates to improvements in attachments for explosive motors, the object of the invention being to produce a means for humidifying the air admitted to the carbureter of the motor prior to its entry into such carburetor, this to be accomplished by passing the said air throughwater. I am aware of the fact that air has been made humid for this purpose before by passing itdireetly through a volume of water, but heretofore there has been no control of the passage of the air through the water to such an extent as to automatically regulate the friction of the air through the water to an extent sufiicient to make the air unlformly moist and of a uniform quantity as it enters the carbureter which is very esential to the successful operation of the motor.

The aim of my invention therefore is to produce a humidifier having an automatic control for the passage of t e air through the water in a predetermined and regulated manner so that the proportions of air and water are always the same, irrespective of the water level in the receptacle.

A further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedin 1y effective for the purposes for which it is esigned.

These objects, I accomplish by means of such structure and relative arrangement of the parts as will fully appear by a perusal of the following specification and claims.

On the drawings, similar characters of reference indicate corresponding parts in the several views.

Figure 1 is a top plan view of my improved humidifier. Fig. 2 is a sectional view taken on a line XX of Fig. 1.

Referring now more particularly to the characters of reference on the drawings, the

numeral 1 designates the water receptacle having a concavo-convex bottom 2 provided at its apex with a draw-off channel 3 having a removable plug 3.

The numeral 4 designates a drain cock communicating with the receptacle 1 for the purpose of fixing the proper level for the water 5.

The numeral 6 designates a chambered member suitably secured to the receptacle 1 and having an upper outlet 7 and a central inlet 8. Arranged within the member (3 are a plurality of bafi'le plates 9, all being centrally orificed and secured to a tube 9 connected with the inlet 8. Said baflle plates are each provided with a plurality of small holes 10, the holes on adjacent plates being arranged alternately with respect to each other.

The numeral 11 designates an air inlet pipe projectin through the inlet 8 and through the tu )e 0" and extending into the receptacle 1, which pipe is provided on its inner end with a flaring outlet 12 provided with a perforated cover 13. In practice, g pipe is connected from the outlet 7 to the inlet of the carlmreter of the motor and then with the suction of the motor. the air is sucked through the pipe 11 and the porous bottom 13 and through the water 15 and thence through the openings in the balile plates 9 back and forth as shown by the arrows in Fig. 2 and thence through the outlet 7 to the carbureter. In this way, the air is thoroughly moistened prior to its entry into the carburetor. If no control is had over the action of the air through the water, an inaccurate proportion may be obtained both of air or water or both and to overcome this difficulty. I have provided an automatic control to maintain the same relative proportions under all conditions and this control consists of a float l=l secured to and supporting the pipe 11 and its outlet 12, which float rests on the water 5, the pipe 11 being slidable through the openings 8 and 9 to allow of its rise and fall with the rise and fall of the water level. Thus, when the float is once adjusted to the needs of a particular motor, the water supply will at all times give the desired moisture, either more or less according to the speed at which the motor may be operated. \Vhen the motor is turning over slowly or under load, a greater amount of moisture will beadmitted to the carbureter for the reason that the float 14 will extend lower into the water but with the higher suction of increased speed, there will be a tendency to slightly lift the float 14 and hence a smaller amount of moisture will be absorbed and more air used which will give better results in theaction of the motor. The sides of the openings 8 and 9 are spaced slightly from the sides of the pipe 11 so as to allow of a slight lateral swinging movement of the pipe 11 to compensate for the different inclined positions which the receptacle 5 may assume with the movement of the vehicle to which the motor may be attached. The perforated baflle plates 9 thoroughly break up the moist air thereby preparing it for admission to the carbureter prior to leaving my device.

In addition to being a humidifier, my improved device may also act as a clarifier for the "air which is especially necessary where the motor is used on machinery operating in dirty and dusty places such as on tractors, trucks and similar structures. In this connection, the movement of the air through the water will remove'dust and dirt which will settle in the bottom'2 of the receptacle 1 from whence it can be removed at will by taking out the plug 3.

In order to prevent any air from being admitted to the member 6 other than through the. pipe 11, I clamp a flexible closure 15 made of canvas or similar material a'i'ound the end of the pipe 11 and around the inlet 8, thus shutting off any possible intake of air through the inlet 8 except through the pipe 11.

From the foregoing description it will readily be seen that I have produced such a device as substantially fulfils-the objects of the invention as set forth herein.

While this specification sets forth in detail the present and referred construction of the device, still in practice, such deviations from such detail may be resorted toas do not form a departure from the spirit of the invention as defined by the appended claims.

Having thus described my invention what 2. A device of' he character described comprising a receptacle carrying Water and.

provided with an outlet, a tube projecting into said receptacle, an open pipe slidably disposed through said tube, a flaring discharge outlet on the lower end of said tube, a perforated cover on the undersideof said flaring outlet, a float interposed centrally in said 'cover and projecting above and below the same, the perforations'of said coverbe' ing arranged around the float, as described.

3. A device of the character described: comprising a receptacle carrying water, said receptacle bein provided with an inlet and outlet, a plurality of perforated bafiie plates in said receptacle, each provided with a cen I tral orifice, a tube pro ecting through said 1 orifices and connected with said inlet, an open pipe projecting into said inlet and through said tube and into said water, a

float on said pipe, the sides of saidi'nlet and I said tube belng spaced from said pipe, as described.

In testimony whereof I aflix my-signature.
